A nutrition student is studying how cells obtain energy. The textbook shows the molecular structure of a 6-carbon sugar that cells routinely break down via glycolysis. Plants store this molecule as starch and animals as glycogen.
The molecule shown is the most common monomer of which class of biomolecule?
- A
Nucleic acid
- B
Lipid
- Ccheck_circle
Carbohydrate (polysaccharide monomer)
- D
Protein
Explanation
Glucose, a hexose monosaccharide with formula C6H12O6, is the building block for polysaccharides such as starch, glycogen, and cellulose.
